Living with Distichiasis-lymphedema syndrome

A genetic condition that causes extra eyelashes and swelling in the legs and feet, often starting around puberty.

Understanding Distichiasis-lymphedema syndrome

Distichiasis-lymphedema syndrome is a genetic condition that affects the lymphatic system, causing extra eyelashes and swelling in the legs.

The lymphatic system moves fluid and immune cells around the body. In this condition, people develop swelling (lymphedema), usually in the legs and feet, most often beginning around puberty. They also have extra eyelashes (distichiasis) from birth, which can rub the eye and damage the cornea. Some also have varicose veins, droopy eyelids, heart differences, or a cleft palate.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • Extra eyelashes (distichiasis)
  • Swelling in the legs and feet (lymphedema)
  • Varicose veins
  • Drooping upper eyelid (ptosis)
  • Light sensitivity (photophobia)
  • Scratches on the cornea (corneal erosion)

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include eye disease specialists, genetic specialists and skin, hair, and nail specialists.

  3. Consider genetic testing

    Changes in FOXC2 are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.

  4. Connect with expert centers

    Lymphatic Education and Research Network may keep lists of experts for this condition.
